About

The Antarctic and Greenland ice sheets contain 99 percent of the Earth's fresh-water ice, according to NASA scientist Lora Koenig. Changes to these regions can profoundly affect sea level and the rate at which the Earth's climate warms or cools, placing them at the heart of research into the planet's future. To understand the current state of the ice sheets and to model the future, scientists spend months at a time on the ice in challenging darkness, frigid temperatures and high winds. Koenig, who is one of these scientists, will discuss how they must learn to solve practical problems of survival and travel through extreme environments while they take precise measurements with specially-designed instruments.
